MEANS FOR SUPPLYING WATER.

Application filed December 19, 1923. Serial No. 681,535.

To all whom it may concern:

Be it known that 1, JOHN ELLERY SAR- GENT, a citizen of the UnitedStates, and resident of Morgan, in the county of Pendleton and State ofKentucky, have invented certain new and useful Improvements in Means forSupplying Water, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification.

My invention relates to means for; supplying water of the type describedin my copending application, filed September 19th, 1921, Serial No.501,653, and has particular reference to improvements in the automaticvalveconstruction set forth in said application.

The principal object of the present invention is to provide an automaticvalve con- 7 Figure 3 is a perspective of the valve stem and plungerconstruction together with the operating lever;

Figure 4 is asection of the frictional valve locking device; 7 V

Figure 5 is an end view of the valve Figure 6 .is a perspective ofcertain of the valve elements disassembled.

The numeral 1 indicates a tank of any suitable shape and constructionand adapted to be sub-merged in the water in a cistern or other sourceof water supply. One of the end heads 2 of the tank is provided with acylindrical valve housing 3, located in the upper portion of the head.The inner end of the housing 3 forms a valve seat 4, and the outer endof said housing is provided with a diametrio cross bar 5, whichisprovided with a central perforation or bearing for a valve stem 6.Mounted on the stem 6 is a frame 7 provided with a solid end 8 and aspider end 9, the same being connected by bars 10. The frame 7 isadapted to bear in the cylindrical housing 3 and to operate .slidablytherein. A rubber or other resilient valve 11 is secured between the endSof the frame and the convex side of a plate 12, the several partsbeingsecur'ed inassembly on the stem by means of nuts 13 and 14, thestem being threaded throughout a portion of its length as shown.

The outer end of the stem 6 of the valve beyond the spider 9 of theframe 7 is provided with two pairs of diametrically opposed notches l5and 16, and flattened 'surfaces 17 between thepairs of notches. The

cross bar 5 is provided with abore 18 in which dogs 19 adapted to bearin either 7 pair of notchesand 16, are inserted.

"Springs 20 secured by set screws 21 compress the dogs against'the valvestem 6.

"The outer end of the valve stem is provided with a collar or nut 22 tolimit the possible inward movement of the valve. g The head 2 of thetank is provided with "lugs 23 in which the two arms 24 of valveoperating mechanism are pivotally secured. The upper ends of the arms 24are connected by a slotted head 25 arranged to receive loosely the stem6 of the valve. Se.- cured on the stem 6 beyond the head 25 is a'nut orshoulder 26, the fingers 27 of the head 25 being arranged to bearagainst either of the nuts 14 or 26 for the purpose of operating thevalve. I

Secured to the head 25 are arms28, to.

the free ends of which a float 29 is pivotally connected. v f 'lhehead 2of the tank is provided with an inlet 30 through which air pressure ismaintained in the tank'for' forcing the water therein outwardly throughthe outlet 31, whence it is supplied to the various points ofconsumption.

A strainer 32 is secured to the intake end of the valve housing 3 toprevent impurities from entering the tank.

The operation of the mechanism is as follows 1 Assuming the tank 1 to befull, the float 29 is in upper position where the fingers 27 will bearagainst the nut 14, forcing the valve against the seat 4. Air pressureintroduced in the tank through the inlet 30 forces the water in the tankthrough 31 to the various points of consumption, as required. As thewater level in the tank goes down the float 29 drops and'the fingers 27the fingers bear against the nut 26, the valve is not afliected by thefingers until the float has dropped to a predetermined point, that isWhere the tank is approximately empty. Until this point is reached, thevalve is held in closed position, partly by the air pressure in the tankand partly by the engagement by the dogs 19 in the notches 16 of thestem.

Vhen the predetermined minimum level is reached however, the fingers 27engage the nut 26 and force the stem 6 inwardly, the surfaces 17 of saidstem sliding between the dogs until the valve is fully opened, when thedogs engage in the notches 15. lVhen the valve is thus opened, the airpressure in the tank is released through the valve and Water from thecistern or other source of supply flows inwardly, raising the float 29until the fingers 27, bearing against the nut 14, again close the valveagainst the friction of the dogs 19.

By this construction I have provided an automatic valve which is highlyefiicient in operation, the frame 7 providing an extended bearingsurface in the housing 3, which so centers the valve stem that theoperation is at all times smooth and accurate.

As an incidental advantage of my valve construction it will be notedthat the release of the air from the tank when the valve is opened iscalculated thoroughly to aerate the water in the cistern or other sourceof supply, thereby keeping it entirely fresh and sanitary.

Having thus fully described my invention what I claim as new, and desireto secure by Letters Patent, is

1. In a device of the character specified, valve mechanism comprising ahousing, one end of said housing being arranged to form a. valve seat, avalve stem, a valve secured to said stem, a bearing frame secured tosaid stem and arranged to bear slidably inside said housing, a float,means for frictionally holding said valve stem in either open or closedposition, and means whereby said float is arranged to operate said valveagainst said friction when liquid in the tank reaches predeterminedlevels.

2. In a device of the character specified, valve mechanism comprising ahousing, one end of said housing being arranged to form a valve seat, abearing in the other end of said housing, a valve stem arranged toreciprocate in said bearing, a valve secured to said stem, a. bearingframe secured to said stem and arranged to bear slidably inside saidhousing, a float, means for frictional-1y holding said valve stem ineither open or closed position, and means whereby said float is arrangedto operate said valve against said friction when liquid in the tankreaches predetermined levels.

3. I11 a device of the character specified, valve mechanism comprising ahousing, one end of said housing being arranged to form valve seat, avalve stem, a flexible valve secured to said stem, a bearing framesecured to said stem and arranged to bear slidably inside said housing,a valve plate having a convex surface arranged to bear against saidvalve to cause it to seat, a float, means for frictionally holding saidvalve stem in either open or closed position, and means whereby saidfloat is arranged to operate said valve against said friction whenliquid in the tank reaches predetermined levels.

4i. In a device of the character specified, valve mechanism comprising ahousing, one end of said housing being arranged to form a valve seat, abearing in the other end of said housing, a valve stem arranged toreciprocate in said bearing, a flexible valve secured to said stem, abearing frame secured to said stem and arranged to bear slidably insidesaid housing, a valve plate having a convex surface arranged to bearagainst said valve to cause it to seat, a float, means for frictionallyholding said valve stem in either open or closed position, and meanswhereby said float is arranged to operate said valve against saidfriction when liquid in the tank reaches predetermined levels.
